Here comes a public service announcement: Eat slower and you'll feel fuller. Oh sorry, wrong one. We meant: Nook Color owners, you can now dual-boot your slate using the specially-created Nook2Android SD card. The card makes installing Android 2.3 a snap and it's now shipping with a dual-boot file courtesy of XDA developers, which means you can choose to boot into the original Nook OS without having to remove the card. You're looking at $35 for an 8GB card, rising to $90 for 32GB. Alternatively, if you're happy to get a bit of oil on your hands, you can try the manual approach. Mmmm, Gingerbread, chew every mouthful.
